Running 10.14 Beta 11, Xcode 10 GM.
I've been diligently updating my apps to support dynamic Dark/Light Mode, but I've run into a problem that has me a bit baffled. I've been following the instructions presented at WWDC to make sure all of my custom views and controls with custom layers get the appropriate color updates when a user switches between Light and Dark Mode. This all seems to be working quite well. However, on controls that have animations in response to mouse events (e.g., Mouse Over) - I seem to end up with the layers reverting back to their previous effective appearance upon mouseover.
The sequence will go like this:
1. Set the Appearance of macOS to Light Mode
2. Start my App
- everything looks appropriate - in light mode.
3. Switch the Apperanace of macOS to Dark Mode
- all of my custom controls/views switch their apperance and things look appropriate - in dark mode
4. Mouse over my custom controls
- my layers suddenly revert back to their light mode appearance even though they looked fine a second ago and I'm still in dark mode
It's like there is some sort of Core Animation layer caching going on that I'm not updating when switching to Dark Mode. I only seem to have this problem when deaing with mouse events. However, I didn't see anything about such a notion when watching the WWDC videos. Anyone have any idea?
